Definition
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Diamictite vs Foidolite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Diamictite vs Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Foidolite. Learn more about Diamictite vs Foidolite in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diamictite and Foidolite, they have various applications in construction industry. The uses of Diamictite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone and that of Foidolite include As dimension stone, Cement manufacture, For road aggregate.
More about Diamictite and Foidolite
Here you can know more about Diamictite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Foidolite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Foidolite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Foidolite is available in black, brown, green, grey, pink, white colors. Appearance of Diamictite is Banded and that of Foidolite is Dull. Properties of rock is another aspect for Diamictite vs Foidolite. The hardness of Diamictite is 2-3 and that of Foidolite is 1.5. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Foidolite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diamictite is light to dark brown while that of Foidolite is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Foidolite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diamictite is heat resistant, impact resistant whereas Foidolite is heat resistant, wear resistant.
